dns: T5959: Streamline dns forwarding service
Streamline configuration and operation of dns forwarding service in following ways: - Remove `dns_forwarding_reset.py` as its functionality is now covered by `dns.py` - Adjust function names in `dns.py` to disambiguate between DNS forwarding and dynamic DNS - Remove `dns_forwarding_restart.sh` as its functionality is inlined in `dns-forwarding.xml` - Templatize systemd override for `pdns-recursor.service` and move the generated override files in /run. This ensures that the override files are always generated afresh after boot - Simplify the systemd override file by removing the redundant overrides - Relocate configuration path for pdns-recursor to `/run/pdns-recursor` and utilize the `RuntimeDirectory` default that pdns-recursor expects - We do not need to use custom `--socket-dir` path anymore, the default path (viz., `/run/pdns-recursor` is fine)
